2011-2014 Chrysler 300/300C Sequential LED Tail Lights Installation Guide

Step-by-step fitting guide for RIGNOX sequential LED tail lights on the 2011-2014 Chrysler 300, 300C, 300S and SRT8.

Important: This online guide is a fitment-aware overview for the matched RIGNOX product. Before removing original parts or connecting wiring, confirm the connector layout, transferred parts, wire routing, and vehicle-specific fastener locations on your exact vehicle.

Safety warning: Do NOT use dielectric grease or weather-sealing grease on connectors or sockets. Grease can cause connection problems and may affect warranty coverage.

Product notes

  • This product covers the outer body-mounted tail lights.

Before you begin

  • Vehicle/product: 2011-2014 Chrysler 300/300C Sequential LED Tail Lights.
  • SKU check: Confirm your kit SKU matches T-C300-11-SR before removing original parts.
  • Power and safety: Switch the vehicle off before unplugging connectors. Disconnect the negative battery terminal when handling wiring, fuse taps, or exposed circuits.
  • Protect the vehicle: Use clean towels or masking tape around painted panels and trim edges. Do not force clips or pry against painted surfaces.
  • No connector grease: Do not apply dielectric grease or weather-sealing grease to connectors or sockets.
  • Rear lamp note: Leave boot trim open until every lighting function passes testing.

Tools and supplies

  • Trim removal tool or panel clip tool
  • Metric socket and ratchet set; confirm the exact socket sizes on your vehicle before removal
  • Phillips and flat screwdrivers
  • Clean microfiber towels and masking tape for painted boot lid and quarter-panel edges
  • Electrical tape and zip ties for securing included harnesses only
  • A helper for brake-light and turn-signal testing

Remove the original tail lights

  1. Open rear access: Open the boot and remove only the trim panels, access covers, or clips required to reach the tail light fasteners.
  2. Expose lamp fasteners: Fold back liners or sound insulation carefully so push clips can be reused during reassembly.
  3. Support the lamp: Hold the lamp with one hand while removing nuts, bolts, screws, or clips.
  4. Disconnect vehicle connectors: Press each lock tab and pull by the connector body, not by the wires.
  5. Release locating pins: Draw the lamp straight rearward. Do not pry against painted body panels.
  6. Repeat on the opposite side: Complete one side fully before starting the other, so the original assembly remains available as a reference.

Install the RIGNOX tail lights

  1. Compare assemblies before mounting: Compare the removed original tail light and the RIGNOX tail light. Transfer bulb holders, seals, brackets, or decorative pieces only where the original assembly clearly carries a part the new one does not.
  2. Connect the main harness: Match each included connector to the corresponding vehicle connector and confirm the lock tab clicks into place.
  3. Secure wiring before mounting: Use zip ties to prevent rubbing, pinching, water pooling, or contact with hinges, latch movement, weather seals, and sharp metal edges.
  4. Seat and fasten the lamp: Align locating pins and check the panel gap against the wing and boot lid before tightening. Tighten original retainers evenly without over-tightening plastic mounts.
  5. Reinstall trim last: Leave trim open until every electrical function passes testing.

Electrical and function test

  1. Test parking/running lights, brake lights, left and right turn signals, hazards, reverse lights, and startup animation if equipped.
  2. Confirm the turn signal sweeps on the correct side and both sides light at equal brightness.
  3. Confirm no bulb-out warning, hyperflash, or flicker appears after two ignition cycles.
  4. After all tests pass, reinstall trim panels and close the boot slowly to confirm no wire is stretched or pinched.

Final check

  • All connectors are fully seated and locked.
  • All included harnesses are secured away from movement, sharp edges, water paths, and heat sources.
  • Both lamps sit flush with even body gaps, properly seated seals, and no trapped harness under the weather seal.
  • All tail light functions test correctly on both sides with a helper operating the controls.
  • No warning lights, hyperflash, flickering, abnormal heat, moisture entry, or loose modules remain after a short function check.

Troubleshooting

  • One tail light does not turn on: Recheck the main connector on that side and the corresponding fuse before assuming a fault in the assembly.
  • Brake, reverse, running, or turn function is wrong: Stop and recheck the connector choice and wire routing before moving pins or changing wiring.
  • Warning, flicker, or hyperflash appears: Confirm the included decoders and LED flash relay are connected exactly as supplied for this vehicle.
  • Trim will not sit flush: Check for a trapped harness, misaligned clip, folded weather seal, or a locating pin that has not seated.
